BED-BOTTOM.

Specification of Letters Patent. PatentedJa'n-i-'11,;1910# sienta,

Application filed August 23, 1909. Serial No. 514,209. I

To all whom it' may concern:

Be it known that l, CHARLES VALLONE, a Y citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Bed-Bottoms, of which the. following is a specification.

This inventionrelates more particularly to flexible bed bottoms of that sort which are composed of wire links joined together in rows and attached to the opposite ends of the bottom frame by springs which permit the bottom to yield or give under the Weight of a person thereon.

The primary object of the invention is to produce' a desirable, comfortable and durable bed bottom of this type in which the component links are constructed, arranged` and joined so as'to simplify and cheapen the construction and also prevent the links from being disconnected in the use or handling of the bed or bedbottom. Thislis of especial importance in bed bottoms that are used on folding couches or beds, asthe links ,are liable to be forced out of engagement when folding the bottom or when a Weight is placed thereon adjacent to the folded portion, as, .for instance, when a person sits on one side of the. folded couch.

ln the accompanying drawings: Figure l is a fragmentary plan of a bed bottom embodying the invention, applied to a ,folding conch frame. Fig. 2 is a transverse sectional elevation thereof, showing the bottom folded. Fig. 3 is a fragmentary perspective view, on an enlarged scale,-showing the joints between adjacent links. Fig. et is a fragmentary plan of adjacent links. Fig. 5 is a sectional elevation in line 5--5, F ig. 4.

Like reference characters refer to like parts in the several figures.`

The flexible bed bottom fabric is preferably lcomposed of substantially U-shaped wire links A arranged and connected to each other in parallel rows runninglengthwise of the bottom, and transverse links B which extend crosswise of the bottom and join the l the bottom can be used with a bottom frame U-shaped. links in adjacent roWs.

Each link A 1s made by-bending a w1re to form parallel 'side bars a provided with hooks a. at the open end of the link, a cross bar a2 at the opposite or closed end of the link, andsmall loops which join the side and cross bars and form eyes a3 at the corners of the closed end of the linkfor the reception of hooks tz of the' Preferably;l

the loops a3 are open have reduced por# r tions or necks, as shown, insteadlof ybeine closed eyes formed by crossing the .sideanil cross bars of the link, as this simplifies. the manufacture' of the links, locates thecrossbar in the same horizontal plane as the side bars and enablesthe links to be connected as presently described. l :Y Each transverse link consists preferably of a straight piece of Wire having itsop-V posite ends bent to form hooks oreyes Z) which encircle or embrace the necks of the loops a3' of the U-links in adjoining rows. By thus' joining the links with the hooks b of the straight links embracing the'necks of the loops a3 of the U-links, instead of passing through the loops, the straightlinks and cross bars of the U-links form in effect transverse chains of straight links, and the ferred directly from the cross bars of the U- links in one roW to the cross bars of the U- links in the next row, which prevents the opening or spreading of the' loops a3 or the bending ofthe side lbars of the U-lin-ks. The hooks Z) of the straight links also cross the openings in the loops a3 and thereby prevent the hooks a of one U-link from being forced out of the loops a of the next link. The hooks a of the U-links and the vhooks b of the' straight linksNare bent around so that when closed their ends 0 abut against the straight 'bars of the links, as shown in Figs. 3 and 5, and extend substantially at riOht angles to the loops engaged thereby and serve as stops to prevent the disengagement of the loops from the hooks. Thus the disengagement ,of the parts is eifectually prevented.

The flexible bottom or fabric composed of links formed and. arranged as described is connected at its ends, by suitable springs D, to the end rails E of a suitable rectangular bottom frame. The bottom is shown in the drawings applied to a folding couchl having end rails consisting of hinged sections, but

lopen ends and corner'floops at their closed ends and arrangedl'in rows with the hooks;

transverse strains on the -bottom are transi of one link engaging in the loops of the nextlink, and links connecting said rows of U-shaped links andhaving end hooks which encircle the loops of the U-shaped links, substantially as set forth.

2. A' flexible bed bottom fabric composed of U-shaped links having hooks at their open ends and open-sided corner loops with reduced necks at their closed ends, and a1'- ranged in rows with the hooks of one link engaged in the loops of the next link, and straight links connecting said rows of U- shaped links and having end hooks whichembrace the necks of the loops of said U- shaped links and prevent the disengagement of the U-shaped links from each other, substantially as setl forth.

3. The combination of a flexible bed bottom fabric composed of U-shaped links having hooks at their kopen ends and corner loops at, their closed ends and arranged in rows ivith the hooks of one link engaging t in the loops of the next link, and links connecting said rows of U-shaped links and having end hooks which encircle the loops of the U-shaped links, substantially as set Y said rows having hooks which encircle said loops and prevent thel disengagement of said interlocked hooks and loops, substantially as set forth.
